That's a problem. If you can find someone with a working copy of the software, they can take the file and export the data as text which you can then import into filemaker 9 or 10. If someone has a copy of filemaker 3 through 6, such an install can conver the copy and then Filemaker 9 or 10 could convert that copy. Whether the result of multiple conversions would be worth the effort? It's hard to tell.
